At Hijikata's insistence she'll grab his mayonnaise-bottle-shaped bazooka and fire it into the portal! She have a glance around to see if there's any way out, too, just in case they need to make a hasty retreat.

In the meantime, whilst his Guardian Spirit manifests to protect him, Hijikata will be summoning fire swords to toss into the portal as well.
